How does concentrated solar power work?

Unlike photovoltaic panels that convert sunlight directly into electrical current, CSP systems focus sunlight to generate thermal energy, which is then used to produce steam and drive a conventional turbine generator. This approach allows for thermal storage capabilities and grid stability features distinct from standard solar PV installations.

Parabolic Trough Technology

The plant’s core technology relies on 1,840 Solar Collector Assemblies (SCAs). Each SCA consists of long, curved, mirror-like reflectors arranged in a parabolic shape. These reflectors track the sun’s movement across the sky on a single axis, continuously focusing sunlight onto a receiver tube positioned along the focal line of the parabola. The receiver tube contains a heat transfer fluid, typically synthetic oil, which absorbs the concentrated solar radiation and heats up to high temperatures. This thermal energy is then transported via insulated piping to a central power block.

Thermal Energy Conversion

In the power block, the hot heat transfer fluid flows through a heat exchanger, transferring its thermal energy to water to produce high-pressure steam. This steam drives a steam turbine connected to an electrical generator, producing electricity for the grid. After passing through the turbine, the steam is condensed back into water and recycled through the system. The parabolic trough configuration used at Genesis is one of the most mature CSP technologies, offering reliable performance in the high-irradiance environment of the Mojave Desert. The system’s ability to concentrate sunlight allows for higher operating temperatures and efficient energy conversion, making it a viable option for large-scale solar power generation in regions with abundant direct sunlight.
